High Resolution Spectroscopy of $$12\atop{Λ}$$B Hypernuclei by the (e,e'K+) Reaction
- Univ. of Houston, TX (United States)
Jefferson Laboratory experiment E89-009 used the reaction (e,e' K+ ) to produce $$12\atop{Λ}$$B hypernuclei from a carbon target. The scattered electrons were tagged at 0° to take advantage of the increased virtual photon flux at forward angles, and the electroproduced kaons were also detected at small angles, ~3°, to minimize the momentum transfer. To do this, a splitter magnet was used to bend the scattered electrons into an Enge split-pole spectrometer and the kaons into a short orbit spectrometer. In addition to increasing the production rate, tagging the scattered electrons at 0 degrees minimizes the optical aberrations on the focal plane of the Enge split-pole spectrometer. In this experiment, the spectroscopy of the $$12\atop{Λ}$$B hypernuclei was studied and excellent energy resolution was achieved, ~ 918 keV. The differential cross section of the ground state doublet was also calculated.
